HD 102272 and Its Planet
HD 102272 is a K0 star 1130 light-years away with one known planet. Its mass is 1.9 solar masses, its radius is 10.1 solar radii, and its temperature is 4910 K. These estimates are each larger than the Sun's corresponding values, except for temperature, which is cooler. The radial velocity method, which detects the wobble a planet's gravity induces in its star's motion, revealed this planet.
HD 102272 b has a minimum mass of 1570 Earth masses, roughly 4.94 times Jupiter's mass and larger than Earth's. Its orbital period is 128 days.
